Better than cheap free inserts supplied by my cheap imported lathe. They are way better than cheap junk. Not as good as Sandvik, but not worth $15 either. I think that's a good golden mean. Good enough to use and get good results but not too expensive. If you're trying to save some money buy these, I won't hesitate to buy Oscarbid inserts in the future but I won't buy any of the cheap 6.99 for 10 nameless junk that's useless. They're pretty decent, especially for the price, better than what comes with cheap imported tools.
